Physical mapping of 5S and 18S-5.8S-26S RNA gene families in polyploid series of Cenchrus ciliaris Linnaeus, 1771 (Poaceae)
The Buffelgrass (Cenchrus ciliaris L., Poaceae) is one of the most important pasturage grasses due to its high productivity and good forage qualities. This species possess a high adaptability to bioclimatic constraints of arid zones and may be used for the restoration of degraded arid ecosystems. Tunisian populations present three ploidy levels (4x, 5x and 6x) with a basic chromosome number x=9...
متن کاملGenotypic Variation for Salinity Tolerance in Cenchrus ciliaris L.
Scarcity of irrigation water and increasing soil salinization has threatened the sustainability of forage production in arid and semi-arid region around the globe. Introduction of salt-tolerant perennial species is a promising alternative to overcome forage deficit to meet future livestock needs in salt-affected areas. This study presents the results of a salinity tolerance screening trial whic...
متن کاملKaryotypic characteristics of Cenchrus longispinus (Hack.) Fernald (Poaceae)
Cenchrus longispinus (Hack.) Fernald (Poaceae), as a weed, is native of America, but has also been introduced in other countries including Iran in the recent years. In this study, karyotypic features in one population of this species was studied. As such, microscopic slides of root tip meristem cells were prepared using the classical squash technique and aceto-iron-hematoxylene staining. The ch...

مطالعه گیاهان مرتعی به منظور شناخت چگونگی رفتار آنها در زیستبومها، اطلاعات پایهای را در مورد نحوه عمل پوشش گیاهی در دسترس قرار می‌دهد که راه را برای شناخت دقیقتر از زیستبومهای مرتعی هموار و امکان برنامه‌ریزی را برای مدیریت صحیح مراتع فراهم میسازد. در این تحقیق آت‌اکولوژی گونه Cenchrus ciliarisدر استان خوزستان مورد بررسی قرار گرفت. نقشه پراکنش تهیه و خصوصیات رویشگاهی شامل پستی و بلندی، اقلیم...
متن کاملAgrobacterium-mediated transient GUS gene expression in buffel grass (Cenchrus ciliaris L.).
The study was conducted to standardize a protocol for Agrobacterium-mediated genetic transformation of buffel grass (Cenchrus ciliaris L.). Embryogenic calli, produced from one-year-old mature seeds of buffel grass, were used as target cells for Agrobacterium-mediated transformation. A. tumefaciens strain LBA4404, harbouring pCAMBIA-1301 or pCAMBIA-2301, was used for co-cultivation with embryog...
